Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a steel saw.

[0002]

[Prior art]

 As shown in FIG. 1, a conventional steel saw 10 includes a handle 11, a frame 12, and a rectangular saw blade 1. The frame 12 is an upside-down U-shaped structure, and supports the rectangular saw blade 1 with parallel arm-shaped structures 13 and 14.

[0003]

[Problems to be solved by the invention]

 However, conventional steel saws 10 cannot be sawed when used in tighter spaces because the height of frame 12 is fixed. For this reason, sawing is inconvenient and the applicability is poor. Therefore, an object of the present invention is to provide a steel saw that can be conveniently used in a small space.

[0004]

[Means for Solving the Problems]

 According to the steel saw of the present invention, a support rod is provided, and a column and a column and a plurality of concave slots (and concave slots) are provided at both ends of the support rod. At the top there is a cross bar with a round slot and a convex point at the end of the bar, the column at one end of the support rod is inserted into the round slot and the convex point is inserted into the concave slot. The bottom of the handle has a quick release assembly, one end of the saw blade is fixed, the end block has a round slot and a convex point at the top of the end block. The other end of the column is inserted into the round slot, convex Into is inserted into concave slot. At the bottom of the end block provided stereotactic cock unit, the other end of the saw blade that is fixed.

[0005] Since the stereotaxic frame is combined with the handle, the support rod, and the end block, the support rod is pivoted and the shape of the frame can be changed. Therefore, it can be conveniently sawed according to the environment.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 2 to 5, a steel saw according to an embodiment of the present invention includes a stereotactic frame 20, a handle 21, an end block 23 and a saw blade 1. The localization frame 20 has one arch-shaped support rod 22, and columns 221 and 222 projecting from both ends of the support rod 22 are provided, and a plurality of concaves are provided around the columns 221 and 222. A slot 223 and a concave slot 224 are provided.

The handle 21 has a horizontal bar 211 at an upper part, a round slot 212 is provided at an end of the horizontal bar 211 corresponding to the support rod 22, and a convex point 213 is provided at a peripheral portion of the round slot 212. ing. The column 221 at one end of the support rod 22 is inserted into the round slot 212, and the convex point 213 is inserted into the concave slot 223 of the corresponding support rod 22. A quick release assembly 30 is provided at the bottom of the handle 21 and one end of the saw blade 1 is fixed.

A round slot 231 is provided at the top of the end block 23, and a convex point 232 is provided around the round slot 231. The column 221 at the other end of the support rod 22 is inserted into the round slot 231, and the convex point 232 is inserted into the concave slot 224 of the corresponding support rod 22. A positioning cock unit 40 is provided at the bottom of the end block 23, and the other end of the saw blade 1 is fixed.

As shown in FIGS. 3, 4 and 5, when the steel saw is used in a tighter space, the quick release assembly 30 and the stereotactic cock unit 40 at both ends of the saw blade 1 are loosened, The support rod 22 is pivoted to change from the upper arched orientation to the lower arched orientation. At this time, since the height of the first half of the support rod 22 is reduced, the steel saw can be used in a narrower space.

As shown in FIGS. 6, 7 and 8, since the support rod 22 is rotatable at 190 °, it is pivoted at 90 ° to one side and arranged in a concave arch shape. Thus, the steel saw can be sawed horizontally as needed for the working space and sawing.

As shown in FIGS. 9 and 10, a mold rod 50 and a mold rod 51 having smaller diameter rods are formed at both ends of the support rod 22. A mold hole 60 and a mold hole 61 corresponding to the mold rods 50 and 51 at both ends of the support rod 22 are provided on the end face of the horizontal bar 211 on the upper part of the handle 21 and the top end face of the end block 23. The mold rod 50 and the mold rod 51 penetrate through the mold hole 60 and the mold hole 61, and the support rod 22 is combined between the handle 21 and the end block 23. As shown in FIG. 11, the mold rod 50 and the mold rod 51 and the mold hole 60 and the mold hole 61 can be formed in other polygons. This embodiment is simple to manufacture and, when combined, is combined as an interchange and can be easily localized.

As shown in FIG. 12, tooth surfaces 70 are provided at the top end surfaces corresponding to the horizontal bar 211 and the end block 23 at the upper end of the handle 21 at both ends of the support rod 22, and are relatively combined. The method of the present embodiment is not limited. Therefore, it can be specifically displayed in a different format based on the principle of the present embodiment.
